M33 – 01/09/2014


I can’t tell you how much of a pain the last 7 months have been in regard to removing the gremlins from my imaging setup.  I’ll go into it in a bit more detail in a separate post, but suffice to say here, my mount has been really testing my patience for the whole time…

Okay then – with that out of the way, here’s my first deep sky image with my newly-sorted setup.  this is M33, the Triangulum Galaxy.  Its a lovely object, though apparently fairly difficult to capture due to its low surface brightness.  This is made up of 29x 4 minute exposures at ISO800 with my astro-modified Canon 1100D.  It’s taken through my Starwave 102ED f/7 refractor, and guided using a finder-guider (with a QHY5v strapped to the back).  The image was filtered from the worst of the light pollution by an Astronomik CLS clip filter.


Single Unprocessed Sub-Frame

The whole lot was stacked in Deep Sky Stacker, and then processed in Photoshop and Lightroom.  Cropped slightly to centre the object.  Just out of interest, see the image to the right for a sample of a single sub-exposure taken that night.  Again – amazing what can be pulled out of it when stacked and processed.  In the sub frame you can only see the core of the galaxy, and a little of the surrounding detail, but certainly nothing like you eventually see when the image is stacked and stretched.

M33 is a very nice looking spiral galaxy in our local group (which also includes us in the Milky Way, and the Andromeda Galaxy).  Its approximately 2.8 million light years away, meaning that the photons hitting my sensor left it way before modern humans evolved!  It’s quite a lot smaller than both the Milky Way and the Andromeda Galaxy, but at 50,000 light years across, it’s still not exactly small…
